Just thirty minutes until she had to study with Sunset.

Adagio couldn’t believe how unlucky she was. She was actually jealous of Aria; Rainbow Dash was as good at ducking the Dazzlings as the Dazzlings were at ducking her. Neither partner wanted anything to do with the other on that side of things. Must be nice.

At least I won’t fail. Adagio had no idea if this project was actually going to make or break her grade in history, but it wasn’t a good idea to ignore her schoolwork. Lest she wanted to spend even more time with VP Luna, that is.

Speaking of, the school’s Vice Principal didn’t look as bored today as usual. Her eyes were actually focused on the trio before her, scanning, almost scrutinizing, them. There was an unsettling eagerness to it all. As though just behind Luna’s stern face was a smile waiting to leap out.

Undoubtedly she wanted to spank someone.

Adagio’s throat felt dry. Yesterday it had felt like the woman had taken quite a bit to the whole “corporal punishment” idea. The glee she had when smacking Aria and Sonata’s rears was… disturbing.

Adagio had already decided she would not be on the receiving end of Vice Principal Luna’s spanks. The way Aria shifted on her butt, even with an extra layer of padding, looked like she was still sore when sitting down. Adagio winced.

Twenty-nine minutes until she had to study with Sunset.

Adagio tapped her heel against the floor. Surely something could speed this up—

FFFBBLAAARRRCH!

She froze, bowels emptying into her diaper before she even knew that noise was from her.

All at once mush dumped into her padding. She didn’t react in time, and was still sitting down too. The mudslide squished between the seat and her rear, coating her butt in brown sludge.

Adagio leapt up, squealing.

FFFPPBLOORRT!

Round two, just when she thought it couldn’t get any better.

She felt her diaper sagging under the heft of her accident, squelching as the mess inside struggled to settle. Warm, gooey mush sloshed inside its padded prison, slapping up against anything and everything in its wake.

It had been so sudden… so violent. And Adagio hadn’t even gotten a warning this time. Usually when she pooped there was some build up, however uncontrollable. It couldn’t be that her sense for this stuff was getting worse, right?

Now the stench hit her nose. Like an uppercut of stink, it made her want to gag instantly. She fought down the urge, biting her lip to gain some control over herself. She couldn’t stop her eyes from watering though.

Every muscle in her body was tightened, waiting for a potential aftershock from that earth shaking dump. But none came, leaving her to stand like a deer in the headlights while the mush settled in her bloated diaper.

Adagio blinked away the water in her eyes, and saw Vice Principal Luna looking at her. Smiling evilly.

“Goodness, you girls weren’t kidding,” she remarked. Then the smell hit her too, and she just had to gag.

To Adagio’s left, Aria was already plugging her nose, at least having the decency to look the other way. Sonata had covered her mouth. Even a few rows away, she could tell this one had been big.

Adagio’s face had never been so red in her entire millenia-spanning life. She wanted to drop dead then and there.

Coughing, Luna eventually recovered. She was pinching her own nose now, fanning away the near visible stink radiating from Adagio’s diaper.

“Alright— Urrf! Ergh.” She coughed again. “You need to be changed. Now.”

“Tell me something I don’t know.” Adagio shivered, jostling the slimy mess between her legs. “Ah! Fff— Sonata!”

“Coming!” At least the idiot was prepared, already raising her backpack full of supplies high in the air.

It made Adagio want to groan. Seriously, how excited can you be to change my diaper? But she held back her complaint. At least someone was willing.

Grumbling, she side-stepped away from her desk, wincing with each crinkly squish. Adagio doubled the size of her gait, just to avoid caress of the warm mush against her inner thighs.

“Let’s go!” Sonata took Adagio’s hand and started leading her to the door. The Siren leader only flushed further, feeling like a child being led around by their mother. She jerked her arm away from Sonata and waddled independently, for whatever that defiance was good for.

And they almost made it to the door.

“Ahem!” Vice Principal Luna cleared her throat.

Adagio stopped, cringing as her mess flopped about in her padding. “What?”

Luna was tapping her foot, arms crossed. “Just where do you think you’re going?”

“The bathroom!” Sonata chirped.

“What, do you want me to get changed here?” Adagio hoped the threat would be enough to deter the VP. She really didn’t want to make good on it.

Luna waved her hand. “Oh, no. But I also don’t want you thinking this is a reprieve. You’re still in detention. I won’t have you dragging your heels just trying to get out of it.”

“I can be fast,” Sonata promised.

Luna glanced at her watch. “Five minutes. If you’re not back by then, I’ll give both of you ten spanks.”

Adagio clenched her jaw. “Excuse me?” She was not going to be treated like this. “What gives you the right?”

Luna’s eyebrow climbed her forehead. “Four minutes then.”

Now Adagio paled. Sonata’s hand snapped around her wrist. “Yes ma’am!” She cried, throwing open the door and yanking her fellow Dazzling through. The threat of another trip over Luna’s lap was a pretty good motivator for her.

“Come on, Dagi!” Sonata pulled her through the halls of Canterlot. Adagio stumbled and struggled to keep up.

“Sonata!” She snapped. Going faster meant reducing her gait, but reducing her gait meant the mess would… “Slow down!”

“Uh-uh!” She picked up the pace, an iron grip on Adagio’s wrist. The nearest bathroom was a good stretch away from the detention room.

Adagio tugged at her skirt, praying they didn’t run into anyone along the way. School had long since ended, and by now most clubs. But stragglers were always possible and she wasn’t going to give anyone a good look at her dirty backside.

squish squish squish

Though, there was nothing she could do about that.

“S-Sonata!” Adagio complained, warm mush exploring far more territory than it had any right to.

They rounded a corner, and Sonata kicked open the bathroom door. Empty, what luck.

Sonata finally let go, dropping to her knees and shrugging her backpack off. “Okay, lie down!” Her hurried tone betrayed her fear.

Adagio rolled her eyes, making sure the door was shut behind them. Sonata was overreacting; sure Luna’s spanks probably hurt, but were they really that bad? At least with the blue moron kicked into high gear she wouldn’t have the find out.

She waddled into the center of the room, stopping just before the sinks. Adagio grit her teeth as she lowered herself. She dipped into an awkward crab stance, doing her best not to just drop on the mud filled sack around her butt.

“Come on already!” Sonata grabbed Adagio’s skirt and tugged, in the most unhelpful way possible.

squish

Adagio’s face contorted. It was a cringe so powerful her skin almost tore. “Sonata!”

“Sorry!” Came her voice in a tone that barely meant it. Sonata was filling the floor with changing supplies, hardly paying attention. A tub of wipes and baby powder joined a fresh diaper on the tiled floor.

Grumbling, Adagio grabbed two fistfuls of her skirt and pulled it up to reveal her diaper. The brown, lumpy padding settled now that it was on solid ground. If she didn’t move, and ignored how warm it felt, Adagio could almost pretend something else had filled her diapers.

“Okay, here we go.” Sonata peeled off the tapes. The illusion was shattered, as she opened the diaper and revealed the awful, smelly mess for what it was. Adagio almost gagged. Sonata definitely did. “Oh Dagi, nooo… It’s everywhere!”

Adagio slammed her fist against the tiles. “Yeah? And who’s fault is that?” It hadn’t been her choice to slosh and jostle her pamps all over the place.

Sonata rolled up her sleeves. “This is going to take a minute…” She plucked a wipe from the tub. Then another. And another. Then a fistful of them.

“Just hurry up!” Adagio whined.

Sonata lifted the Sirens legs up, sliding her well used diaper out of the way. Adagio’s butt had precious seconds to enjoy being free of the padding. She actually unclenched her jaw a bit at the sensation of cool air against her cheeks.

Then cold wipes found her rear and sent her yelping. “Warn me next time!” Adagio demanded.

“Sorry.” Sonata attacked the lingering muck. Adagio just stared around the room awkwardly, crossing her arms. She never knew what to do during this part, but she certainly was not going to make eye contact.

Wipe after wipe came and went. Soon Adagio was swearing Sonata had used half the tub. Normally she wouldn’t care, but with that ticking clock… “Aren’t you finished yet?”

“I’m trying!” Sonata insisted, just as much worry in her voice. “You’re very messy, okay?”

“It can’t be that bad!” Adagio fired back.

“Well you are.” Sonata put her hands on her hips. “And stop talking so much, I’m trying to change you!”

“What, you can’t listen and wipe at the same time?”

“I’m bad at multitasking and you know it!” Sonata pulled her backpack around and started to dig through it.

“Well get better now!” Adagio couldn’t believe how much time this blue idiot was wasting. How much longer did they even have now? She checked her watch, but that did a fat load of good. She hadn’t checked the time when they left, so who knows when they were supposed to be back? And Sonata still had her hands in the bag and not on the wipes. “Stop wasting time you id—mmph?!”

She nearly choked on the thing Sonata shoved in her mouth. The Siren held a finger to her lips and whispered “shhh” before returning her attention to the diaper change.

As the cold wipes returned, they snapped Adagio out of her initial surprise. Morbid curiosity seeped into her brain, all questions coming back to the same: What had Sonata put in her mouth?

Her tongue snaked around a rubbery bulb that now rested between her teeth. A plastic guard bumped up against her lips. Adagio reached up and pulled it out of her mouth, but she already knew what it was.

A pacifier.

“Sonata!” She sat up, clenching the bright pink device and fighting an even pinker blush. “What the hell?”

Sonata flinched. “I— You’re weren’t being quiet, so…”

“Errgh! I can’t believe you would even bring this thing to school with you?”

“I like it…” Sonata mumbled.

Adagio leapt to her feet, skirt falling over her barebottom

“Wait, your diaper!” Sonata exclaimed. She stood, chasing after Adagio who stalked to the nearest stall. “What are you—?”

Adagio kicked the stall door open and threw the pacifier into the toilet. Sonata’s cry of surprise was drowned out when Adagio flushed it.

“Unbelievable,” Adagio grumbled. She dusted off her hands, brushing past Sonata before lying back down on the ground.

“Aww…” Sonata frowned back at her. “That was my favorite paci.”

“I’ll let you buy a new one,” Adagio grumbled. “Now hurry up!”

With a pout, Sonata knelt back down to unfold Adagio’s fresh diaper. Her usual smile didn’t return.

They returned to detention to the sound of Luna’s tsking. Adagio was already groaning before the Vice Principal even stood up. She didn’t even need to look to know there was a wry little smile on her face.

“Five and a half minutes.” Luna tsked again. “I believe I was very clear to you girls.”

“Yes ma’am…” Adagio spat out.

“Mmhmm…” Sonata mumbled.

Luna gave a sigh that wasn’t really a sigh. Slipping her new paddle out from the desk, she twirled it in hand. She crossed to them, waving the wooden plank with an eagerness that made Sonata gulp.

“You know what I have to do now, don’t you?” Her lips poked upward in a smirk.

Oh screw you. Adagio narrowed her eyes. They knew damn well VP Luna didn’t have to do anything. But she clearly wanted to. And Adagio was only okay with sadistic pleasure when she was the one experiencing it.

Luna pointed her paddle to the girl who still had a little fire in her. “Adagio, come here.” She made the girl march to the center of the room, a chair already set up and waiting. She was so ready for a chance to redden the last Siren bottom and wasn’t even trying to hide it.

Sonata kept her head down, fidgeting with the edges of her skirt. But Adagio planned to face her fate bravely. Sure, the blue moron had cried, and even Aria was left whimpering, but she wasn’t going to give Luna the satisfaction of either.

The Vice Principal sat down. “Go ahead and remove your skirt.”

Adagio ground her teeth. They hadn’t had to do this yesterday. But she choked down her pride and slipped her skirt off. Her thighs got a taste of cold air, and she couldn’t even close them to avoid it. Her diaper enjoyed announcing its presence to the room, crinkling as she bent back up and bulging out to give her rear the roundest shape anyone had ever seen.

Luna snickered.

Adagio fired an accusatory glance her way, cheeks flushed. Choice words leapt to her tongue and the momentum almost carried them out. She barely kept her jaw clenched.

“At least you did get a change after all,” Luna mocked the white padding. “You certainly don’t smell like you did.”

Adagio’s face grew redder. It was true. A mess that big meant the stink would be trailing her for ages. One more reason to look forward to her study session later.

Luna gave her lap a pat. “Lie down.”

Adagio could help but feel a twinge of jealousy as she took her place on the older woman’s lap. She remembered not-so distant past where she used to exert that kind of control. This little role-reversal couldn’t last forever, right?

A hand gripped a fistful of padding, hoisting Adagio’s diaper up high. “H-Hey!” she cried at the sudden wedgie. Her cheeks were made vulnerable in an instant. The one possible benefit her diaper could have provided, gone.

SMACK!

“Ah!” Adagio cried out. Already, she’d lost. The surprise ripped away her chance to be the immovable wall to Luna’s spanks.

“One.” Luna said as the sting began to set in. Fire spread over her butt. It wasn’t even—

SMACK!

“Errf!” Adagio swallowed that one.

“Two.”

SMACK!

Her flesh rippled at the impact. Adagio bit her lip, not making a sound for that one. But the illusion was already shattered.

Sonata still wasn’t looking up, though with each success paddling she flinched.

SMACK! SMACK!

Aria didn’t look like she was getting vicarious enjoyment out of the experience. Her own time on that lap was too fresh. She rubbed her rear, watching the clock instead of Adagio.

SMACK! CRACK! SMACK!

Tears blinked into Adagio’s eyes. NO! She wasn’t going to cry. Despite each hit lighting up her butt with a red glow, she wasn’t going to cry.

SMACK!

No matter how much it hurt, she—

SMACK!

A single tear escaped to her cheek.

“Annnnd ten.” Luna released Adagio from the wedgie. The sensation of bunched up padding was still there, even as the diaper settled over her red bottom noisily.

Adagio scrambled to her feet, wiping her face before anyone could notice. Though just the action gave it away.

The VP had a smug look on her face. Was her thirst for revenge against them finally complete? Adagio hoped so. Now she could truly sympathize with the other Dazzlings. Her spanks may be up, but it felt like the paddle had branded its shape against her rear. She fiddled with her diaper, trying to push as much cool padding as she could over her battered butt.

She retrieved her skirt like a wounded puppy, and with an approving look from Luna slinked back to her seat. Adagio winced just by sitting down. The throbbing sting wasn’t going away anytime soon.

“Alright, Miss Dusk, it’s your turn now,” Luna addressed her next victim. Sonata whimpered her acknowledgement before walking over. Adagio couldn’t blame her.

She looked at the clock and groaned.

Just twenty minutes until she had to study with Sunset.
